Painting Tool

What do you call your artwork done in Paint tool Sai or any Painting Software?

i need it to make a signature for my Artworks i've made in Sai..
For example, you are a photographer and you're name is Vanessa Hudgens. So you use a signature for your photos and your siganture is ; Photography by Vanessa Hudgens
So what do i call mine? Digital Artworks by Vanessa Hudgens? pls reply ASAP

It is called DIGITAL ART, so Digital Art by Vanessa Hudgens is fine to use: http://en.wikipedia.org/wiki/Digital_art

If you use digital drawing mediums (pencil, pastel, markers, etc....) to create your art, it can be called a DIGITAL DRAWING.

If you use digital painting mediums (oil, watercolor, etc...) to create your art, it can be called a DIGITAL PAINTING: http://en.wikipedia.org/wiki/Digital_painting
